What property opposes changes in current flow through a coil?

Inductance is the property that opposes changes in current flow through a coil. When the current through a coil changes, the magnetic field around the coil also changes. According to Lenz's law, an induced electromotive force (emf) is generated in the coil that acts in opposition to the change in current. This means that if the current is increasing, the induced emf will try to decrease it, and if the current is decreasing, the induced emf will try to increase it. Thus, inductance effectively resists changes in the current, enabling the coil to maintain a stable current flow under varying electrical conditions.

Other properties mentioned, such as capacitance, resistance, and voltage, do not specifically oppose changes in current flow in the same way that inductance does. Capacitance deals with the storage of electrical energy in an electric field, resistance refers to the opposition to current flow, and voltage is the potential difference that drives the current. While all these factors can influence electrical circuits, it is the inductance that specifically acts to counteract changes in current through a coil.
